This invention relates to 'farmi ng machines and more piu'ticularly' to a novel tractor which is particularly but not necessarily adaptable for farm work. f

One of the primary objects oit the present invention is to provide a tractor which will be universal in its nature, that susceptible 4lfor use 'tor all kinds oll farm worlr.

Another salient object of the invention is to provide an .improved tractor which is en tensible laterally, so that the width thereof can be varied, whereby the tractor can be eliiciently used 'lor plowing and the like where a narrow gage tractor is needed and effectively used 'igor planting and cultivating where a wide gage tractor is desirable.

A further object ot the invention is the provision of a tractor embodying a main trame carrying the engine and associate part and an auxiliary frame carrying the ground engaging element with novel means for connecting the auxiliary 'frame with the main trame whereby the auxiliary 'trame may be extended laterally to change 'the width of the tractor to permltthe same to be used tor different purposes.

A further object oit the invention the provision ol novel means for associating the auxiliary frame with the main frame whereby the auxiliary frame can be conveniently adjusted and the ground engaging element readily drivenfrom the prime mover or engine. i

A further object oit the invention is the provision ot novel endless traction chains carried by the auxiliary frame with novel means :tor steering the tractor by braking the drive to one of the other ot' the said driving f traction chains.

A further object of the invention 1s the provision ot novel means for associating the :tai-ming,implement with the auxiliary frame, said means permitting the `ready raising and lowering ot the implement.

A still further object of the invention is to provide a farm tractor of the above char acter which will be durable and ciiicient in use, one that will be simple and easy to manutact-ure and one which can be placed upon the market at a reasonable cost.

With these and other objects in view, the invention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described, claimed, and illustrated in the accompanying drawings, in which drawings:

Figure ll is a detail perspective view of one of the main drive plates of the traction chain. f

Referring to the drawings in detail, wherein similar reference characters designate cor responding parts throughout the several views, the letter .A generally indicates the improved tractor, which comprises a main iframe l5 and an auxiliary iframe 50.

The main i` me l5 comprises a pair oil spaced longitudinally extending side bars 1G and i7 which can bx constructed 'trom chane and these side beams are connected toga; er at their forward terminals by a transvrse channel beam 1S. Adjacent to the rear end ofthe beams 1G and 17 are a pair of spaced transversely extending channel beams 19 and 2O which extend laterallybeyond the side beams 16 and 17 and are connected by the side longitudinally extending beams 21 and 22. The transverse beams 19 and 20 are bolted or otherwise secured to the main side beams 1G and 17 in any desired way. The main traine has mounted thereon adjacent to the lorward end thereof the prime mover 23 which is oro the internal combustion engine type and this engine may' be ot any desired size and :mal-e best suited for the purpose intended. The engine is cooled by any suitable conventional water cooling system 24` ot large capacity.r yThe propeller shaft 25 has incorporated therewith any desired type of clutch mechanism'26 which is actuated Vby a toot pedal 27 arranged adjacent to the drivers seat 2S. This seat 2S is bolted or otherwise secured to the rear transverse trame bar 20 and projects slightly rearwardly beyond the trame. A transmission 29 is also provided and this transmission includes a gear shift lever 80 which also terminates adjacent to the drivers seat. Projecting laterally ofthe transgears 33. These shafts have also secured .ated by rearwardly extending cured to steering` shaft` sections 3S and 39.

These shaft sections extend into the casing et() ot the control mechanism which is actuated by a steering column 41 and wheel Ll2. This wheel 4-2 is arranged directly in front of the drivers seat. By turning the wheel the brake is actuated on one side/or the other ot' the frame according to the direction Vot the turn and this torins the means for vguiding the tractor,V as will be later described.

In order to permit the operation of farming machinery from the tractor such as wood saws or the like the propeller shaft 25 torwardly of the vmotor is provided with a beveled gear 43 which has meshing therewith a beveled cog 44 secured to a cross shalt actuating the various farm machinery.

The auxiliary frame 50 comprises frame sections 51 and 52 arranged on opposite sides of the main `frame 15 beyond the longitudinal side bars 21 and 22. Each of the side 'trames 51 and 52 of the auxiliary tra-me 50 includes a pair ot spaced upper channel beams 53 and a pair of lower spaced channel beams 54. These pairs of channel beams can be suitably bolted together and support iront and rear pairs ot bearing blocks 55 which receive the laterally projecting ends 5G and .ing movement ot these 57 of the front and rear axles 5S and 59 respectively. Each of these axles are constructed substantially the saine and include a pair of sliding sections 59 mounted in sleeves 6() and G1 secured to the main traine 15 by depending bearing blocks G1. By sliding the sections 5S and inwardly or outwardlv o the sleeves (50' and 61 the position or is laterally wiJ h respect to the n'iain Lrauic and thus the active width ot the tractor can be readily adjusted. Any desired type ot lockmeans can be provided tor holding the axle sect-ions in adjusted position, such as set screws or the lilf'e. lt to he noted that the axle sections and the sleeves are polygonal shaped in cross section whereby swingaxles is prevented. rl`he portions of the axles arranged betweenthe oi upper and lower channel beams 53 and 5 rotatably receive the trent and rear pull wheels 82 and G5 and the peripheries ot these wheels are provided with drive teeth G1. lr und each pair of front and rear pull whiels is trained an endless traction belt 55. traction belt 65 iuigedly connected sections GG and sections are preterably niade no ot parallel side plates 67 to which are ilted ground plates G8. The icai terminals et the ground plate 68 `are preferably rolled as at (il) to provide ground engaging traction cleats G9. rlhe ends et the si G7 are provided with over-looping ...lly dit'ected pivot ears 70 and these pivot ears the adjacent side plates are connected by pivot bolts 71. The t bo fs 71 are received between the teeth t the wheels G2 and G3 so that upon roion et' the wheels the chains or traction l be operated. The ytrent wheels (32 63 consti vripheries oit the wheels G3 are provided with ring gears 7 2. Disposed in front of the rear axle sleeve 61 is a supporting sleeve 72 ute powerY wheels and the inner pewhich is This sleeve supports a jack shaft `73 which includes a pair of drive sections 74;

`outer ends ot the aelr shaft sections 74 and 7 5 have keyed or otherwise secured thereto drive pinions 7 7 which mesh with the crown gears 72 on the drive wheels 63. Y These drive gears 77 are confined between the upper il e side trames can be adjustedv traine bars 53 and the wheels 63 so that upon movement of the side trames of the auxiliary trame 5() the jack shatt sections will be moved therewith. It is to be noted that the side trames ot' the auxiliary frame 50 carries suitable bearings for the jackjshaft section.

In use of the improved tractor the engine, clutch and transmission are operated in the usual weT and the tractor can be conveniently driven over a. lield.` When it is desired to turn the vtractor it is merely necessary to stop one of the traction beltsor chains and this is accomplished by operating the steering wheel which brakes one or the other ot the jack shaft sections.

I have provided novel means for connecting the various tarm implements to the tractor, such as plows, planters, cultivators and the like so that the implements can be lifted on the tractor and this means can be slightly varied for each type otl farm implement.

In the present instance I have shown one preferred form of connecting a 'farm iinplement to the tractor and this means inchicles a transverse draw har 8O which has its terminals slidably and rocliahly mounted in eyes 8]. ilormed on the inner upper frame hars 53 of the auxiliary frame 50. Thefdraw bar 8O adjacent to its opposite ends .is provided wit-li rearwardly extending arms 82y which are provided with depending feet 88 at their terminals. These feet are rigidly connected by clamps 84 to the draw bars 85 et the farming implement. Adjacent to the center of the draw bar 80 is an inwardly eX- tending crank arm 86 which has pivotally connected thereto a link 87 which is in turn pivotally connected to the ythrow lever 88. This throw lever is pivoted to a segmental rack bar 89 and a suitable hand control pawl which. can lie used for all farming purposes and in iif'hiehthe width oit the traine can be readily adjusted.

Changes .in details may be made without departing 'from the spirit `or scope of this invention, hut what I claim as new is:

A. tractor comprising a main tra-me, a power plant on said trame, an "auxilliary iti-ame including side members 'disposed laterally ol the init-in trame each consisting of upper and lower bars, blocks between and spacing said bars, axles non-rotatably carried by said blocks extending inwardly toward the main kframe and having their inneil ends polygonal shaped in cross section, tront and rear wheels carried by said axles, rigid trent and rear sleeves secured to the main trame ot' polygonal shape in cross section slidably receiving the polygonal ends of said axles, a transmission for the power plant carried by the main frame including op-y positcly extending drive shafts, a bearing sleeve, a jack shaft including a pair of rotatably and slidable sections mounted in the hearing sleeve, means for operating the sec-r tions romthe drive shaft, and means for operating certain of the wheels from the outer terminals ot the Jack shatt sections.

In testimony whereof I afliX my signature.
